Hi Aditya,
I tested your solution and it works great. I cannot see any problems
in my output. I wish I had your Tex programming skills, I am trying
to learn the language myself from the TexBook (D.Knuth) but I still
have a long way to go.
Well, I do not understand Tex. What I usually do is look at the
context source, which is much easier to read than latex internals, and
then copy from there, play around a bit, and sometimes things
work.
Another test to check that the formula numbers work as expected
\placeformula[kem-chapter-eqn11]
\startformula
\cases{
\eqalign{
\widehat{\vec{x}} = - \vec{x} \cr
\widehat{t} = t \cr
}}
\quad \text{resp.} \quad
\cases{\eqalign{
\widehat{\vec{x}} = \vec{x} \cr
\widehat{t} = -t \cr
}}
\stopformula
How about
\definemathmatrix
[group]
[left={\left\{\,},right={\right.}]
\startformula
\startgroup
\NC \widehat{\vec{x}} \NC= - \vec x \NR
\NC \widehat t\NC= t\NR
\stopgroup
\quad \text{resp} \quad
\startgroup
\NC \widehat{\vec{x}} \NC= \vec x \NR
\NC \widehat t\NC= -t \NR
\stopgroup
\stopformula
There is also startstop cases, but that does not give the correct
spacing in this case. May be useful otherwise.
\startformula
\startcases
\NC \widehat{\vec{x}} \MC= - \vec x \NR
\NC \widehat t\MC= t\NR
\stopcases
% Read MC as Math Column, there is also the usual NC
% which gives a text column
\quad \text{resp} \quad
\startcases
\NC \widehat{\vec{x}} \MC= \vec x \NR
\NC \widehat t\MC= -t \NR
\stopcases
\stopformula
HTH,
Aditya

[NTG-context] Myway on using mathalign
Hi Aditya,
I read you MyWay document on using \startalign and I was
interested in section 4.2 numbering subformula's
Everything works fine as stated in your nice document.
One thing I want to do with a set of subformula's is
to reference the main formula but still subnumbering the equations
like
\starttext
\incrementnumber[formula]
\placesubformula
\startformula
\startalign
\NC div \vec{E} \NC = \epsilon_{0}^{-1} \rho \NR[eqn1:A][a]
\NC rot \vec{E} \NC = 0 \NR
\NC div \vec{B} \NC = 0 \NR[eqn1:B][b]
\NC rot \vec{B} \NC = \mu_{0} \vec{j} \NR
\stopalign
\stopformula
See \in[eqn1] for the static Maxwell equations, where we are
going to examine \in[eqn1:A] a bit further
\stoptext
Hope you can help
Thanks
Wim

Excellent document! Can we persuade you to write similar texts
indeed
for the other math environments? And you can remove the actual
code for the intertext, it will be included in the core for
the upcoming release.
watch the header line (esp last two pages)
never use \setupheadertexts this way (in page stream) since you get a sync
problem then
at the top of your document say:
\setupheadertexts[section]
or
\setupheadertexts[{\getmarking[section][both]}]

Excellent document!
indeed
Thank you for the encouragement.

environments?
The only other math environments that I understand are matrix and
cases. I will try to include matrix, esp how to emulate amsmath's
aligned family of environments using context's matrix.
And you can remove the actual code for the intertext, it will be
included in the core for the upcoming release.
I will change this once I do an update at my end. I can not install
the beta right now, as I have some deadlines and do not want to break
anything.
watch the header line (esp last two pages)
Thanks for catching this.

I see that now.
at the top of your document say:
\setupheadertexts[section]
or
\setupheadertexts[{\getmarking[section][both]}]
Done that to my local copy. Will make a new version with some clean up
and additions later this month.

Hi, I have written some examples on how to use startalign. Patrick has placed it on the garden. It can be downloaded from http://dl.contextgarden.net/myway/mathalign.pdf In case someone is interested, the source is available at http://dl.contextgarden.net/myway/mathalign.tex This is how I understand math alignment. Let me know if there is a mistake somewhere.
